BECAUSE TO FIND THE VERTEX, YOU USE THIS FORMULA: -B/2a
which is: -2x/2(x^2)
Answer:
d)
Step-by-step explanation:
Equation of circle with center at point (h, k) and radius, r.

This problem:
(x − A)^2 + (y − B)^2 = C
The center is (A, B).
The radius is sqrt(C).
Answer: d)
To achieve balance, the momentum on both sides must be
equal so that it cancels out. Momentum is simply the product of mass and
distance, therefore:
50 pounds * 6 ft = 100 pounds * X
X = 3 ft
Hence B must be placed 3 ft from the pivot.
